is the grass greener

I’ve put a post recently about my partner and I who don’t get on after 3 years. We have a 1 year old and it’s just not the same when we’re good for 2 days it’s fine but when we’re bad for the rest of the week It’s really bad. Like hate. It’s sound terrible because I don’t hate him but I hate him in that moment like I could just kill him. I don’t know weather leaving thinking the grass will be greener and I’ll find a man who worships the ground I walk on (and I him) because he just dosent give a shit. He acts like I’m nothing special every valentines, birthday and Christmas is a last minute thing there’s no thought that goes into it I don’t care about the gift I care about the thought that goes into it. Like his bday is April and I planned somthing on janurary. We kiss twice when he comes how from work and when we go to bed and when I say kid I mean kiss. We never “make out” unless it’s sex which is very rare also. I’m so miserable and unsatisfied I just don’t know what to do anymore. Will leaving be the worst thing I do
